Please fill out the fields below so we can help you better. Note: you must provide your domain name to get help. Domain names for issued certificates are all made public in Certificate Transparency logs (e.g. https://crt.sh/?q=example.com), so withholding your domain name here does not increase secrecy, but only makes it harder for us to provide help.
My domain is: happyhourmenu.ca
I ran this command:
sudo crontab -e:
0 4 * * 1 /usr/bin/certbot renew --quiet >> /var/log/le-renew.log
I received this email:
Attempting to renew cert (happyhourmenu.ca) from /etc/letsencrypt/renewal/happyhourmenu.ca.conf produced an unexpected error: The nginx plugin is not working; there may be problems with your existing configuration.
The error was: NoInstallationError(). Skipping.
All renewal attempts failed. The following certs could not be renewed:
1 renew failure(s), 0 parse failure(s)
My web server is (include version): Nginx 1.10.3
The operating system my web server runs on is (include version): Ubuntu 16.04.4
My hosting provider, if applicable, is: DigitalOcean/self-hosted
I can login to a root shell on my machine (yes or no, or I don’t know): Yes
I’m using a control panel to manage my site (no, or provide the name and version of the control panel): No
The strange thing is that everything worked fine when I first installed the certificate, and the cron job has been auto-renewing it weekly since late July with no issues. This is the first time there’s been a problem!
